SPECIFICATION forming part of Ltrersrarent No. 382,652, dared May 8,1888.

Application tiled J une 8, 1887.

To all whom it may concern:

Be it known that I, FoEDYoE ALLEN LYMAN, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Vapor-Burners and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates toA improvements in vapor-burner stoves; audit consists in certain features of construction and in combination of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a vapor-burner stove embodying my invention. Fig. 2 is a view, partly in plan and partlyin section, of theretort, heating-chamber, and connected mech anism; and Fig. 3 is a View in side elevation, partly in section, of the same parts. i A represents the frame of the stove; A', the stove-top a, the burners, and a the vcomminglingtubes leading to the extreme burners.

B is the retort, the same having an enlarged end or generator, B. from the gasoline-container tothe retort,v the one section thereof, b', being enlarged,as shown in Fig. 2. A casing, C, incloses the'commingling-chamber c and combustion or heating chamber c', the casing C being mounted on and made to rotate a limited distance on the retort. This casing is provided with receivingnozzle C', extending'laterally, and by turning the casing in the one direction or the other this nozzle is made to present toward the jetorifce of the needle-valve d, or toward the lightingpipe E. Y

F is the lighting-cup, that may be used in the ordinary way in connection with the needle-valve d when the nozzle O is turned in this direction. The lighting-.cup is made integral with an arm, F', and with a ange or hood, f, the former being rigidly attached to the casing C, and the latter, by engaging with the valve-arm D, forms a stop .to limit the movement of the lighting-cup and casing in the one direction, the hood f serving also to direct the ame from the lighting-cup or from the lighting-tube along up the arm D to heat the latter. An arm, f,'extends laterallyfrom serial No. 240,616. (No model.)

.the lightingcup, this arm on the free end thereof having an upwardly-projecting lug,

f, that by engaging the armv D limits theA movement of the lighting-cup in the' other direction.

G is an airreservoir of large capacity, and

is provided with' an air-pump, G', of ordinary construction for supplying air under pressure to the reservoir. A safety-valve, g, is conf nected with the reservoir, to prevent a great pressure being had in the latter bythe action of the air-pump.

VISI is the gasoline-container, the same being provided with a filling-nozzle, H, the latter .beingclosed by a removable screw cap or plug, h. An air-pipe, I, leads from the reser- Voir into the container, and discharges at or near the bottom of the latter. The supplypipe b aforesaid extends to near the bottomof the container H, and the -pressure of air admitted from the reservoir through the pipe I forces the gasoline from the container up through the supply-pipe and through the re= tort. The air passing through the pipe I, being discharged at or near the bottom ofthe containerr H, bubbles up through the gasoline,

thereby becoming carbureted in its passage, and of course this ca'rbureted air accumulates on top of the gasoline inthe container.y Y

` rlhelighting-pipeE is connected with the top part of the container H,'and is provided with' a stop-valve, E', on opening which the carbu! reted air escapes from the mouth ofthis pipe, and may be directed' into the nozzle C when the latter is turned in this direction. The discharged carbureted air, as it commingles with the atmosphere in' its passage to thenozzleG,v A

becomes highly combustible, and -may be ignited'with a match and used for lighting the stove instead of using the lighting-cup F. A branch pipe, discharges toward the light. ing-cup, and this jet of flame therefrom strikes the hood f, and is thereby directed along up the arm D for heating the latter,. after which by turning .back the lighting-cup and the chamber C to direct 'the nozzle G toward the' needle-valve d the latter may be opened and-v the stove operated in the ordinary mannen The air-pipe I is provided with a stop-valve, I', that' should be closed in lling the container, Vso as not to exhaust any air-pressure that at the time may be' had in the air-reser- IOO voir, as such waste of air would necessitate extra labor at the air-pump. In case a slight leakage is had at the air-pump, such as ordinarily would do 11o harm and would not perhaps be noticeable, yet' in standing, for instance, over night, such leakage might produce the pressure in 'the reservoir to such an extent that the great pressure in the gasolinecontainer might force some gasoline through the pipe I into the reservoir. A single occurrence of this kind would do no special harm; but if repeated many times more gasoline than desirable might be accumulated in the air-reservoir. A drip-pipe and valve might be had at the bottom ofthe reservoir to drain oi` this gasoline; but in so doing the air-pressure in the reservoir would likely be exhausted. In view of these difficulties I have devised the following: The induction end of the pipe I terminates close to the bottom of a cup, pocket, or depression, i, preferably made at the bottom of the reservoir, as shown in Fig. 2, and any gasoline that has been forcedinto the reservoir would be in this depression or cup and covering the mouth of the pipe I, and consequently the duid in the cup would be forced back into the container as soon as the airpressurein thereservoir should become greater than the air-pressure in the container. In

place of such depression or pocket aforesaidV located at the bottom of the reservoir, a cup,

i', might be placed, for instance, in the position shown in dotted lines in Fig. 1, some distance from the lbottom of the reservoir, the end ofthe pipe I terminating in this cup, and such device would operate in the same manner as aforesaid. The location, therefore, of the pocket, depression, or cup at the bottom ofthe reservoir, although preferable, is not essential. Vhere the cup is located some distance above the bottom of the reservoir, it should be of such ample size as would not likely overflow. The advantage of having the cup or pocket at the bottom of the reservoiris, that ifvit should overflow the fluid would drain back into the cup and be returned to the container.

Apartition, K, isloeated between the burner and air-reservoir, to protect thelatter from the heat of the burner and from consequent expansion. lVhere the stove is started by means of a lighting-cup in the ordinary manner, it requires some little time to fill the cup by reason of the small opening of the needlevalve, and much more time is required to heat the arm D to vaporize the gasoline in the retort, after which the gas admitted to the commingling-chamber from the needle-valve has to be lighted, the whole operation of lighting the stove requiring usually about tive minutes time.

With my improved device by means of the lighting-'pipe the carbureted air may be turned on and ignited in the first instance, thereby simultaneously directing a jet of flame against the arm D and directing a jet of vapor into the combustion-chamber, from which latter the heat passes up around the generatingchamber, so that in a few seconds the lightingcup and chamber C may be swung back and the needle-valve opened to discharge vapor into the nozzle C', and when this latter is donc the valve E is closed and the gas escaping from the needle-valve orifice is ignited in the combustion-chamber by the llame fed from the ex cess of Vapor remaining in the heating-chamber, after which the valve E' is closed,and the stove may then be operated in the usual manner. The whole operation of lighting the stove by means of the lighting-pipe requires usually only about thirty seconds.

rlhe handle of the valve E is preferably connected by a rod or link, E, with the lightingcup and arranged substantially as shown in Fig. 2, the relation of parts being such that with the valve E closed the casing C and the lighting-cup will be in position with the nozzle C presenting toward the needlevalve,and with the valve E open the nozzle C will present toward the lighting-pipe. With this arrangement, if the needlevalve is opened before the valve E is closed, the vapor from the needle-valve will be and remain lighted inthe combustion-chamber, such lighting being done by the jet of flame from the lighting-pipe. The operator, therefore, has only to manipulate the handle of the valve E in starting the burner. rlhe so-called safety-valve g may be of any ordinary construction, but is not,as its name would imply, for protecting the airtank from bursting with overpressure, as the air-pump furnished for this purpose is not intended for producing even approximately a pressure that would endanger the tank. Only a limited pressure can be used with the apparatus; otherwise the burners could not be lighted. The function, therefore, of the valve g is to keep the pressure within the limits that will render the burner and combustion-chamber operative-that is to say, to prevent an overblast or an excessive blast at these points.

Vhat I claim is- 1. The combination, with mechanism for supplying carbureted air, substantially as indicated, and an oil-supply pipe, of a lightingpipe for discharging the carbnreted air to the burner, said lighting-pipe having two outlets, a valve located in the lightingpipe for simultaneously controlling both outlets, a movable heating-chamber having a nozzle, and arm D, substantially as set forth.

2. The combination, with an airreservoir, a pump for supplying air to same, gasolinecontainer, substantiall y as indicated, and a pan-like receptacle located within the air-container, of an air-pipe connecting these two vessels, one end of the air-pipe being located at or near the bottom of the gasoline-container and the other end of said pipe terminating near the bottom of the receptacle, substantially as set forth.

3. The combination, with a reservoir, an airpump, and a gasoline-container, of an air-supply pipe leading from the reservoir into the IOO IIO

container, said air-pipe having an overflow vessel connected with the induction end of the pipe, substantially as set forth.

6; The combination, with an arm, D, alighting-pipe; a valve therein, a retort, and a ro-` tating casing provided with a receiving-nozzle, of alighting-cup rigidly attached to the rotating casing, the said cup being connected by a link with the valve-handle of the lightingpipe, whereby the'cup is -operated by the movement of the valve, substantially as set forth.

In testimony whereof I sign this specification, in the presence'of two witnesses,this 21st day of May,1887.
